Borszéki J. — Inczédy J. - Gegus E. - óvári F. : Evaluation by Pattern Recognition Methods of Laser- Microspectral Analysis Data of Roman Coins = Fresenius Z. Analy Chem 410-413, p. 314.(1983) Data produced by the non-destructive method of laser-microspectral analysis were treated by a pattern recognition method in order to characterize silver antoniniani coins produced in various mints of the Roman Empire in the middle of the 3rd century. The aim of the work was to classify the sample coins according to their origin from different mints, and the assignment of some coins of "uncertain origin" to these classes on the basis of their chemical composition, i.e. the content of the significant minor and trace elements: Au, Zn, Ni, Bi, Sn, Pb. The Karhunen-Loeve transformation and the K-nearest neighbours pattern recognition methods were applied for processing the analytical data. As a result of the investigations nearly all the coins studied could be assigned to the presumed groups of the mints considered and objective support was given to numismatists in aid of their coin-classification work. Borszéki J. — Inczédy J. — Óvári F. — Gegus E.: Use of pattern recognition methods for the evaluation of analytical data of third century antoniniani coins = Acta Archaeologica Academiae Hungaricae 35, pp. 87-93.(1983) Non-destructive laser-microspectral analysis of a number of Roman silver coins of the 3rd century has been carried out. The concentrations of the accompanying and trace elements were determinded. The coins contained 12—17 metals. At least four of these elements could diffuse into the surface layer of the coins from the soil (Ca, Mg, Al, Si). Six metals (Au, Zn, Ni, Bi, Sn, Pb) were selected by a computer method as significant ones for the determination of the origin of the coins. A pattern recognition method and the Euclidean distance function were used to evaluate the analytical data. Using this method, and strict mathematical conditions, almost each coin could be assigned to one of the three groups corresponding to the mints. Objective supporting evidence has been provided to help to decide a number of debated numismatic questions which, so far, have only been tackled from historic and art-historical grounds.

Two classes were produced for the calculation of data originating from various mints of the Roman Empire (Viminacium and Antiochia). Applying the known classes, some coins of "uncertain origin" were classified.
